A nurse on a pediatric unit is receiving a report from an assistive personnel (AP). Which of the following clients should the nurse plan to visit first?

Rationale: A. Diabetes insipidus can lead to profound dehydration due to excessive fluid loss. A urine specific gravity of 1.002 indicates very dilute urine, supporting the concern. This child is at immediate risk for hypovolemic shock, so the nurse should assess them first. B. A pulse oximetry of 95% is within acceptable range for a child with asthma, suggesting no acute distress at this time. C. Roseola with a fever of 39°C is expected; while monitoring is needed, it's not the highest priority. D. Pain of 6/10 in sickle cell anemia is concerning and requires attention, but it is not as emergent as potential fluid imbalance in diabetes insipidus.
